-5x + 10x +3 =5x + 6 how many solutions does it have

For this case we must solve the following linear equation:

Adding similar terms from the left side of the equation:

Subtracting from both sides of the equation we have:

Thus, equality is not fulfilled. So the equation has no solution.

No solution

idk

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
